Without getting into too much of a conspiracy theory, if you wanted to kill or delay Trump's indictment in NY then the elected official is the guy to do it, not the prosecutors, they are officers of the court and must not be involved or know the reason. Trump's NY troubles are of little interest to his base who won't understand it anyway, it would be out of sight and be behind closed doors. Trials in Georgia are on TV and republican officials will be testifying against Trump for election cheating and directly challenging the big lie under oath. It will most likely happen this summer and it will get national wall to wall TV coverage and in Futon Co, he has a very good chance of being convicted, the sentencing might be in the fall.
Perhaps they are saving Donald's virginity for the right moment and will pop his cherry on live national TV with the nation glued to the tube. I would, if it meant the house and senate in 2022 and would quietly and carefully arrange to make it happen. Bragg just ain't that big a fool, but a call from someone in the party might have changed his mind and a six or nine month delay is nothing in the legal system. He is the key to making it happen in Georgia on national TV this spring or summer and he is elected, so he's covered, for now.
